[jira] Commented: (HBASE-1925) IllegalAccessError: Has not been
initialized (getMaxSequenceId)
[ https://issues.apache.org/jira/browse/HBASE-1925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768335#action_12768335 ]
stack commented on HBASE-1925:
------------------------------
Here is code:
{code}
public long getMaxSequenceId() {
if (this.sequenceid == -1) {
throw new IllegalAccessError("Has not been initialized");
}
return this.sequenceid;
}
{code}
Up in the open we see:
{code}
byte [] b = map.get(MAX_SEQ_ID_KEY);
if (b != null) {
// By convention, if halfhfile, top half has a sequence number > bottom
// half. Thats why we add one in below. Its done for case the two halves
// are ever merged back together --rare. Without it, on open of store,
// since store files are distingushed by sequence id, the one half would
// subsume the other.
this.sequenceid = Bytes.toLong(b);
if (isReference()) {
if (Reference.isTopFileRegion(this.reference.getFileRegion())) {
this.sequenceid += 1;
}
}
}
{code}
Can we get a bad storefile?
